| titleOfInvention | Oxygen-curable mercaptoorganosiloxane compositions containing both redox and iron carbonyl compounds and method of forming higher molecular weight products therefrom |
| abstract | ABSTRACT OXYGEN-CURABLE MERCAPTOORGANOSILOXANE COMPOSITIONS CONTAINING BOTH REDOX AND IRON CARBONYL COMPOUNDS AND METHOD OF FORMING HIGHER MOLECULAR WEIGHT PRODUCTS THEREFROM Compositions, stable in the absence of oxygen, are formed by mixing the following substantially in the absence of oxygen: (A) 100 parts by weight of at least one mercapto-functional organosiloxane containing at least two mercapto-functional substituents per molecule; (B) a catalytic amount of an iron carbonyl compound catalyst selected from the group consisting of Fe(CO)5, Fe2(CO)9, Fe3,(CO)12, dicyclopentadienyldiiron tetracarbonyl, butadieneiron, tricarbonyl and cyclohexadieneiron tricarbonyl, preferably from 0.1 to 6 parts by weight of catalyst per 100 parts by weight of part (A); (C) optionally, at least one filler; and (D) 0.1 to 6 parts by weight per 100 parts by weight of a redox compound such as copper (II) sulfate or iron (III) oxide. The compositions polymerize or sure to form higher molecular weight products upon exposure to oxygen. The use of a redox compound appears to increase the cross-link density of the cured composition and results in harder resins and more durable elastomers. An important novel feature of the redox compounds is that their use enables one to formulate compositions which cure to low-modulus elastomers possessing excellent unprimed adhesion to many common substrates such as glass, metal and concrete. Such low-modulus elastomeric compositions are very desirable for use as building sealants. |
